Both donned casual looks as they jetted out of LAX. Rob wore a black Adidas hoodie and matching sweatpants, paired with Givenchy Sandals and gray socks and an L.A. Dodgers baseball cap. Chyna sported a black and white T-shirt and matching Lycra leggings, paired with black shoes and a pale blue purse. She wore her hair, which she changes often, in long curls.

On Friday, the two went shopping at a clothing store, where she filmed and posted a Snapchat video of her beau trying on an outfit and showcasing his weight loss.

Rob was hospitalized and diagnosed with diabetes in December after battling weight issues since at least 2014. He has in recent months shed a considerable amount of weight and Chyna appears to have helped him shed the pounds.
